do you also see neighbor disconnect events? if you have no neighbors, you won't be able to receive any new stream fragments/chunks.

is the UnpublishNotify for the stream you're interested in, or an old/stale stream in the group? the event has the stream name.

the NetworkChange event suggests that the local network interface (ethernet/wifi) is changing IP addresses, or becoming temporarily disabled. its address could change if a wifi base station reboots, or a DHCP lease expires, among other reasons. RTMFP can often survive network interface address changes, but not all circumstances can be survived (especially if one end or the other of a connection is behind a different NAT, or has a firewall, etc).

This issue seems to have resurfaced with Flash Player 12.0.0.70 on Windows 8.1, where the UnpublishNotify is being dispatched. Does anyone know if this is a Flash Player issue or Windows 8.1 (or both)?

If there any update on this ticket ? Or any one able to make Multicast work on Windows 8.1 ? Is there any other resource available to make this work on Windows 8.1 ? We have clients using IP Multicast moved to Windows 8 and IP Multicast is dropping after few minutes . We are afraid we will not be able to continue using multicast on windows 8.1 . Will really appreciate some input on this ticket from Adobe .
